Vegetable Seed Production-
Field Standards in India

Continued ..................

Specific type field standards:

To maintain the requisite genetic purity and to achieve the high level of seed standards during seed production it is essential to have field standards. Since the seed production programme organized by public as well private sectors organization at different locations, seasons and of various class, thus the field standards has to be maintained uniformly during the execution of the seed programme in field. The field standards is of two types, the first one is general requirements which include the isolation distance for foundation and certified seed and second is the specific requirements comprising offtype, objectionable weeds and plants affected by seed borne diseases. The objectives of general and specific requirements are to maintained genetic purity avoiding the genetic contamination and ultimately to meet the seed standards. Specific requirements: The maximum permitted (%) of off type, plant affected by seed borne diseases and objectionable weed plants are given below.
